Not getting all the channels- only 2 - 13 and auto set isn't finding the others. Apreciate any help.


Look in the setup menu, set is now set to air or antenna which on cable will only allow channels 2-13------------if on cable or such switch the setting to catv/cable and not to air/antenna.

I have my Hitachi 42HDT79 42 in. Plasma Television on my wall and I have no voice, just a loud squeeing noice. It doesn't matter what volume its on.


It of course may be a audio problem in the set (main board) but is a box or anything external being used for sound on the set? Same problem with a DVD etc the only thing connected to the set?

Turned on set....screen all black except a dark blue rectangle in center which reads:Failed to receive broadcast [E202]


That message is presented when a selected digital channel is too weak to decode. Let us hope that something was accidentally changed:

Is the channel legitimate?
Is the antenna/cable still connected (to the Digital input)?
Go into menu - setup - channel setup. Is the selection of either cable or air channels correct for your situation?
Use menu - setup - Antenna Setup-DIGITAL to examine the signal strength. Is there nothing at all, or is it just a question of strength?

Odds favor a change in channel setup that you would not have made intentionally, or a simple physical problem (input cable, etc.). Start from scratch, and check the settings and connections you originally made. Hopefully it will be simple and cheap!

How do I set up model 50v500 hitachi tv to receive hd


You have to have an hd cable box it is different from your run of the mill digital cable box. Most people rent them from their cable provider. This will enable you to get HD channels through them

TRutech 15" LCD does not pick up all channels


Check your TV settings and make sure your tuning is set for cable (may say "cable" or "CATV"). Right now you'll probably find it set for "air". If the TV is set to tune off-the-air, cable channels 2 through 13 work normally, but above that they aren't detected. Once you set the tuning mode to cable, rescan channels and you should have them all.

Cannot watch channels past 13


Your tuner settings must be set on broadcast instead of cable. Below channel 13, they use the same frequencies so it doesn't matter. Find the tuner settings page in the menus and change the cable/air setting.
